The one in Maine, the more correct of the two was pulled, it was for sale locally according to the ad. The one still for sale is not very correct and missing most postal hardware on the body. Could be a fun vehicle, but you really have to know what your buying if bidding on this one.
I don't know too much about postal A's,but years ago I sold a cowl to somebody in Maine that told me it came from a postal truck.It didn't have the cut off cowl posts like the one in that picture.It had a rounded over cap,that went across the whole cowl,right down to the belt line.I have no idea if it was postal,but the guy that spotted it said it was and had to have it.
Yes, bobs picture is of the late 31 commercial cowl, no provision for doors and hinges. used for the body by others chassis, does appear to have the remains of Mail Truck wood on right side. If no wood is attached tell tale sign it was a mail truck would be a second hole bored below factory hole for choke rod on lower firewall. The earlier 31 procurement still considered late 31 utilized the roadster cowl and it had provisions for doors and hinges. Both cowls had the indented firewall.
